Heat Recovery with Recirculation Bypass

Reference project
Rotary heat exchangers for high-temperature applications are one of the specialities of R. Scheuchl GmbH. Certain applications require that the temperature of the flue gas or exhaust air downstream of the heat exchanger does not fall below a specific value, in order to prevent the formation of aggressive condensates. A recirculation bypass can be used for this purpose, mixing heated supply air with the incoming fresh air. The design and delivery of all system components, such as ducting, fans and filter stages, are provided from a single source.
In order to make use of the energy contained in heavily contaminated exhaust air at 230 °C, a Scheuchl rotary heat exchanger for high-temperature applications is recommended. In addition to their extremely low pressure drop, rotary heat exchangers offer the major advantage of being able to be cleaned automatically with compressed air and water. This ensures optimum heat transfer even after many operating hours. With a rotor diameter of 2,890 mm, air volumes of 65,500 m³/h (20 °C) can easily be handled.
